' SAFETY RAZOR Filed Sept. 18, 1951 Inventor 6 JOSEPH BORNEMANN F1:- 4

By NW ZZM'V A [for my Patented July 19,1932- PATENT OFFICE JOSEPHBORNEHANN, OF TBENTON, NEW JERSEY mm JaAzon I Application filedSeptember 18, 1931. Serial 110. 563,471.

The principal object of my invention is to provide a-safety device whichis readily, easily and securely attachable to the well known razor ofthe straight type in common usetoday. Another object of my invention isto provide a safety device ofthe character described which willabsolutely preclude the possibility of cutting ones self when shavingwith a straight razor to which my safety 1 device has been attached,even when the arm is given a sudden movement. v

Another ob'ect of my invention is to provide a body ormed of one pieceof spring material bymeans 'of which the guards of the safety device maybe secured and positioned in the proper relationship to the razor edge.Still another object of my invention is to so mount the guardsmechanically, that the planes of the guards will constantly be parallelto each other and-to the plane of the razor, also so that the edges ofthe guards, which are equally spaced on each side of'the razor will atall times be equally distant from the razor edge, despite the angle ofthe parallelogram of which the guards form opposite ides.

Furthe objects and advantages will appear in the following descriptionin which like characters designate like parts and in which:

Fig. 1 is a view of the safety device on a straight razor shown in dotand dash lines,

Fig. 2 is. an end view in the direction of 2-2 of Fig. 1,

Fig. 3 is an end view in the direction of 3-3 of Fig. 1,

Fig. 4 is a plan view of the body member before it is bent toshape,

Fi 5 is plan view of one of the guard mem ers,

Fig. 6 is an end view of Fig. 5, and Fig. 7 is a view on line 77 of Fig.1 showing t e device in operation.

In the drawing the straight razor is shown in dot and dash lines at 1,the handle not being shown. This razor has a body 2 and the edge .3, thecontour of which is similar to the edge 4 of the guards 5, and coincidestherewith in Fig. 1. The safety device has the metal body member 6 madeof a single shaped piece of suitable spring material as is clearly shownin Fig. 4 before bending I on lines 7 '7 In the center is therectangular opening 8, through which'the razor projects. The body member6 has projectmg lugs at 9, 10, 11, 12, 13 and 15; cut out portions .at14, 18, and 19; a small hole at 17 and a projecting tab 16 for purposesto bedescribed. The body member 6 is folded upon line 77 to.substantially V-shape as is shown in cross-section in Fig. 3, the pairsof lugs 9, 10, and 11, 12, together forming projecting studs or fixedpivots for members to be described. The fold lines 20 and 21 form sto sfor the razor, and the sides of the b0 y 6 form spring clamps around thebody 20f the razor as shown in Fig. 7 to securely hold the device inposition. Covering the front end of the V-shaped body is the tab 16 bentover to position, the lug 15 bending over the opposite side of the bodyto secure the parts. Likewise lug 13 bends over the opening 14 in theopposite side of the body. as appears in Fig. 3. I,

Side members or guards 5 are each formed of a blank of suitable materialas shown in Fig. 5, with the wires 22, and 23 in place to be securedinto position. The end 24 of the secures the wire- 23 in position, thiswire having two projecting ends that serve as pivots.

. The guards 5 are secured to each other by means of similar crossmembers 27, 28, and 29 which are drilled to receive the projecting endsof the wires 22 and 23 in a loosely jointed connection. Thus it will beseen that on one end of the body 6 the two arms 25 and the 5 other, andwill always be parallel to a plane drawnthrough the fixed pivots, inwhich lies the edge of the razor, so that the bottom members 27 and 28form a four sided. loosely jointed parallelogram. The member 27 has apin 29 in it which projects inwardly into the hole 17 in the tab 16; themember 28 rocks on the pivots formed of lugs 9 and 10.; andthe member 29rocks on the pivots formed of lugs 11 and 12. It is to be understoodthat the wires 23, 23' are secured at each .end in the members 28 and 29to prevent endwise accidental removal of said members, and the guards 5,5pivot about the wires 23, 23.

The openings 18 and 19 provide clearance for the Wires 22, 22, whenthedevice assumes the position of Fig. 7 I The depending portions 30, 30 ofthe whereby the guards move automatically to protect .either side of therazor.

3. In a safety device'for razors, a palr of guards, a support forholding the guards at opposite sides of a razor blade, and a parallellinkage system on the support for maintaining the guards 1n freeswinglng relation to the razor blade with their lower edges at all timesapproximately in the same plane as the cutting edge of the razor blade.

In testimony whereof, I afiix my signature.

JOSEPH .BORNEMANN.

guards 5, 5 have the contour of line 4 which 1 is the exact contour ofthe razor edge, and this may'change with a change in contour of therazor. 4 I

It will be seen, as in Fig. 7, that due to the stationary pivotsprovided respectively by studs. 9 and 10, 11 and 12, and 29 and theloose pivots at 22, 22 and 23, 23, the planes of the guards 5, 5 willalways be parallel to each edges of the guards will constantly beequally ing from the spirit of the invention shown and hereafter'setforth in the appended claims.

- 'Iclaim:

1.'In a safety device for razors, a body.

' member for attachment to a razor blade-said body member having pivotsat each end adjacent the back and the edge of the blade, supportingmembers rockable on said pivots, and guard members pivotally mounted onsaid supporting members parallel to the median plane of the blade at asuflicient distance therefrom to permit the guard members. to

swing, freely for automatically guarding either side of the blade, thelower edge of the guard members beingat all times substantially in thesame plane as the edge of the razorblade. v

. 2. In a safety device for razors, a resilient clip adapted to be heldon a razor blade, guard members at opposite sides of the razor the loweredges of the guards being parallel to the edge of the razor, and aparallel linkage system for connecting theguards to the clip and to eachother in free swinging relation,
